It's the Flash system of angles that is stuffing you around. Flash uses an awkward coordinate system. As it gets to 360 it does its calculation and you get 360 which unfortunately makes it skip around to that point in the opposite direction. Can you make the code available please, so I can see it. I am not that good at maths or actionscript yet so I would really like to see how it actually works.
You should be able to find the solution on some tutorial websites like www.flashkit.com
